What is 4/5 + 5/12?

Here's how you add

4

5

&plus;

5

12

Step 1

Of course, you can't add two fractions if the denominators (bottom numbers) don't match. To get a common denominator, multiply the denominators together. Then we fix the numerators by multiplying each one by their other term's denominator.

Now you multiply 4 by 12, and get 48, then we multiply 5 by 12 and get 60.

Do the same for the second term. We multiply 5 by 5, and get 25, then multiply 5 by 12 and get 60.
